DETAILED DESCRIPTION OF THE EMBODIMENTS

Hereinafter, embodiments will be explained in detail with reference tothe accompanying drawings.

Some of the parts which are not associated with the description may notbe provided in order to describe embodiments of the disclosure and likereference numerals refer to like elements throughout the specification.

As used herein, the term “and/or” includes any and all combinations ofone or more of the associated listed items. Throughout the disclosure,the expression “at least one of a, b or c” indicates only a, only b,only c, both a and b, both a and c, both b and c, all of a, b, and c, orvariations thereof.

The terms “and” and “or” may be used in the conjunctive or disjunctivesense and may be understood to be equivalent to “and/or.” In thespecification and the claims, the phrase “at least one of” is intendedto include the meaning of “at least one selected from the group of” forthe purpose of its meaning and interpretation. For example, “at leastone of A and B” may be understood to mean “A, B, or A and B.”

It will be understood that although the terms “first,” “second,” etc.may be used herein to describe various components, these componentsshould not be limited by these terms. These components are only used todistinguish one component from another. For example, a first elementreferred to as a first element in one embodiment may be referred to as asecond element in another embodiment without departing from the scope ofthe appended claims.

As used herein, the singular forms “a,” “an” and “the” are intended toinclude the plural forms as well, unless the context clearly indicatesotherwise.

It will be further understood that the terms “comprises” and/or“comprising” “includes” and/or “including”, “have” and/or “having” areused in this specification, they or it may specify the presence ofstated features, integers, steps, operations, elements and/orcomponents, but do not preclude the presence or addition of otherfeatures, integers, steps, operations, elements, components, and/or anycombination thereof.

When a layer, film, region, substrate, or area, or element is referredto as being “on” another layer, film, region, substrate, or area, orelement, it may be directly on the other film, region, substrate, orarea, or element, or intervening films, regions, substrates, or areas,or elements may be present therebetween. Conversely, when a layer, film,region, substrate, or area, or element, is referred to as being“directly on” another layer, film, region, substrate, or area, orelement, intervening layers, films, regions, substrates, or areas, maybe absent therebetween. Further when a layer, film, region, substrate,or area, or element, is referred to as being “below” another layer,film, region, substrate, or area, or element, it may be directly belowthe other layer, film, region, substrate, or area, or element, orintervening layers, films, regions, substrates, or areas, or elements,may be present therebetween. Conversely, when a layer, film, region,substrate, or area, or element, is referred to as being “directly below”another layer, film, region, substrate, or area, or element, interveninglayers, films, regions, substrates, or areas, or elements may be absenttherebetween. Further, “over” or “on” may include positioning on orbelow an object and does not necessarily imply a direction based upongravity.

The spatially relative terms “below”, “beneath”, “lower”, “above”,“upper”, or the like, may be used herein for ease of description todescribe the relations between one element or component and anotherelement or component as illustrated in the drawings. It will beunderstood that the spatially relative terms are intended to encompassdifferent orientations of the device in use or operation, in addition tothe orientation depicted in the drawings. For example, in the case wherea device illustrated in the drawing is turned over, the devicepositioned “below” or “beneath” another device may be placed “above”another device. Accordingly, the illustrative term “below” may includeboth the lower and upper positions. The device may also be oriented inother directions and thus the spatially relative terms may beinterpreted differently depending on the orientations

Sizes of components in the drawings may be exaggerated for convenienceof explanation. In other words, since sizes and thicknesses ofcomponents in the drawings are arbitrarily illustrated for convenienceof explanation, the following embodiments are not limited thereto.

Additionally, the terms “overlap” or “overlapped” mean that a firstobject may be above or below or to a side of a second object, and viceversa. Additionally, the term “overlap” may include layer, stack, faceor facing, extending over, covering or partly covering or any othersuitable term as would be appreciated and understood by those ofordinary skill in the art. The terms “face” and “facing” mean that afirst element may directly or indirectly oppose a second element. In acase in which a third element intervenes between the first and secondelement, the first and second element may be understood as beingindirectly opposed to one another, although still facing each other.When an element is described as ‘not overlapping’ or ‘to not overlap’another element, this may include that the elements are spaced apartfrom each other, offset from each other, or set aside from each other orany other suitable term as would be appreciated and understood by thoseof ordinary skill in the art.

In the specification, an expression such as “A and/or B” indicates A, B,or A and B. Also, an expression such as “at least one of A and B”indicates A, B, or A and B.

In embodiments below, when a component is referred to as being “on aplane,” it is understood that a component is viewed from the top, andwhen a component is referred to as being “on a schematic cross section,”it is understood that the component is vertically cut and viewed fromthe side.

It will be understood that when a layer, region, or component isreferred to as being “connected” or “coupled” to another layer, region,or component, it may be “directly connected” or “directly coupled” tothe other layer, region, or component and/or may be “indirectlyconnected” or “indirectly coupled” to the other layer, region, orcomponent with other layers, regions, or components interposedtherebetween. For example, it will be understood that when a layer,region, or component is referred to as being “electrically connected” or“electrically coupled” to another layer, region, or component, it may be“directly electrically connected” or “directly electrically coupled” tothe other layer, region, or component and may be “indirectlyelectrically connected” or “indirectly electrically coupled” to theother layer, region, or component with other layers, regions, orcomponents interposed therebetween.

Also, when an element is referred to as being “in contact” or“contacted” or the like to another element, the element may be in“electrical contact” or in “physical contact” with another element; orin “indirect contact” or in “direct contact” with another element.

“About” or “approximately” as used herein is inclusive of the statedvalue and means within an acceptable range of deviation for theparticular value as determined by one of ordinary skill in the art,considering the measurement in question and the error associated withmeasurement of the particular quantity (i.e., the limitations of themeasurement system). For example, “about” may mean within one or morestandard deviations, or within ±30%, 20%, 10%, 5% of the stated value.

In the following examples, the x-axis, the y-axis and the z-axis are notlimited to three axes of the rectangular coordinate system, and may beinterpreted in a broader sense. For example, the x-axis, the y-axis, andthe z-axis may be perpendicular to one another, or may representdifferent directions that may not be perpendicular to one another.

Thepad portion PP may cover or overlap the conductive portion MP from theoutside of the conductive portion MP and may include an elastic materialto prevent the curved display panel and/or the curved window from beingphysically damaged in a case that the curved display panel disposed overthe support portion SPP is coupled with the curved window by theconductive portion MP. For example, the pad portion PP may include aflexible material such as rubber. In an embodiment, the pad portion PPmay include fluid. The pad portion PP may directly contact theconductive portion MP. For example, the first flat conductive portionMP1, the second flat conductive portion MP2 and the curved conductiveportion MP3 of the conductive portion MP may directly contact the firstflat pad portion PP1, the second flat pad portion PP2, and the curvedpad portion PP3 of the pad portion PP, respectively.

The roller portions RP may be disposed on the surfaces of the first andsecond flat film portions GP1 and GP2 which may face the magneticportion IMP. The roller portions RP may be directly disposed on thesurfaces of the first and second flat film portions GP1 and GP2 whichmay face the magnetic portion IMP.

The extended portions of the first and second flat film portions GP1 andGP2 along the second direction DR2 from the other end of the first flatmagnetic portion IMP1 may be bent in the first direction DR1 by theroller portions RP. The roller portions RP may tightly fix the first andsecond flat film portions GP1 and GP2 in the manner of bending them asdescribed above, and accordingly in a case that the display panel may bearranged or disposed on the curved guide film GP to form a curveddisplay panel, it may be possible to prevent the waviness of the curveddisplay panel due to the guide film GP.

In step S10 of forming the curved display panel 30, a panel windowcoupling member 40 may be formed on an outer surface (or one surface) ofthe curved display panel 30. In step S50 of attaching the curved displaypanel 30 to the curved window 50, the curved display panel 30 and thecurved window 50 may be attached via the panel window coupling member40.

In step S10 of disposing the display panel 30 over the support portionSPP, the display panel 30 may be disposed on the guide film GP coveringor overlapping the support portion SPP, and in step S10 of forming thecurved display panel 30, lower portions of the guide film GP may betightened by the roller portions RP.

The extended portions of the first and second flat film portions GP1 andGP2 along the second direction DR2 from the other end of the first flatmagnetic portion IMP1 may be bent in the first direction DR1 by theroller portions RP.

The roller portions RP may tightly fix the first and second flat filmportions GP1 and GP2 in the manner of bending them as described above,and accordingly in a case that the display panel 30 may be arranged ordisposed on the curved guide film GP to form the curved display panel30, it may be possible to prevent the waviness of the curved displaypanel 30 due to the guide film GP.

Referring to FIGS. 4 and 5, between step S30 of disposing the curvedwindow 50 and step S50 of attaching the curved display panel 30 to thecurved window 50 by the electrostatic attractive force, the supportportion SPP, the guide portion GUP, the curved display panel 30 and thepanel window coupling member 40 formed or disposed on the curved displaypanel 30 may be moved to the one or a side in the second direction DR2so that the uppermost end (the one or an end in the second direction DR2or the curved panel portion 33) of the curved display panel 30 may becoupled with the uppermost end (the one or an end in the seconddirection DR2 or the curved window portion 53) of the curved window 50via the panel window coupling member 40.

Subsequently, referring to FIGS. 6 and 7, the curved display panel 30and the curved window 50 may be attached by the electrostatic attractiveforce acting between the magnetic portion IMP outside the curved window50 and the conductive portion MP of the support portion SPP (step S50).

In step S50 of attaching the curved display panel 30 to the curvedwindow 50 by the electrostatic attractive force, attachment may beperformed sequentially from portions adjacent to the uppermost ends (theone ends in the second direction DR2) of the curved display panel 30 andthe curved window 50 to the lowermost ends (the other ends in the seconddirection DR2) thereof.

As described above, the magnetic portion IMP may be sequentiallyoperated from the one or a side to the other or another side in thesecond direction DR2. The magnetic portion IMP may include the firstsub-magnetic portions IMP1 a to IMP4 a, and the second sub-magneticportions IMP1 b to IMP4 b which may be sequentially arranged or disposedfrom the uppermost end (the one or an end in the second direction DR2)of the curved magnetic portion IMP3 to the lowermost end (the other oranother end in the second direction DR2) of each of the flat magneticportions IMP1 and IMP2. The first sub-magnetic portions IMP1 a to IMP4 amay be disposed in the curved magnetic portion MP3 and the first flatmagnetic portion IMP1 of the magnetic portion IMP, and the secondsub-magnetic portions IMP1 b to IMP4 b may be disposed in the curvedmagnetic portion MP3 and the second flat magnetic portion IMP2 of themagnetic portion IMP.

The first sub-magnetic portions IMP1 a to IMP4 a may be sequentiallyoperated in the arrangement order from one or a side to the other oranother side in the second direction DR2. The second sub-magneticportions IMP1 b to IMP4 b may be sequentially operated in thearrangement order from one or a side to the other or another side in thesecond direction DR2. The overlapping portions in the first directionDR1 among the first sub-magnetic portions IMP1 a to IMP4 a and thesecond sub-magnetic portions IMP1 b to IMP4 b may be simultaneouslyoperated. For example, the first-first sub-magnetic portion IMP1 a ofthe first sub-magnetic portions IMP1 a to IMP4 a and the second-firstsub-magnetic portion IMP1 b of the second sub-magnetic portions IMP1 bto IMP4 b may be simultaneously operated. The first-second sub-magneticportion IMP2 a of the first sub-magnetic portions IMP1 a to IMP4 a andthe second-second sub-magnetic portion IMP2 b of the second sub-magneticportions IMP1 b to IMP4 b may be simultaneously operated.

In an embodiment, the first sub-magnetic portions IMP1 a to IMP4 a maybe sequentially operated from the one or a side to the other or anotherside in the second direction DR2, and then the second sub-magneticportions IMP1 b to IMP4 b may be sequentially operated from the one or aside to the other or another side in the second direction DR2.

In an embodiment, the support portion SPP and the curved display panel30, which have been disposed on the guide film GP to be curved, may bemoved to the one or a side in the second direction DR2 so that theuppermost end (the one or an end in the second direction DR2) of thecurved display panel 30 may be disposed adjacent to the uppermost end(the one or an end in the second direction DR2) of the curved window 50placed between the curved display panel 30 and the magnetic portion IMP.Then, as described above, the magnetic portion IMP may be operated suchthat an induced current may be sequentially applied from the one or aside section in the second direction DR2, which may be adjacent to theuppermost end (the one or an end in the second direction DR2) of themagnetic portion IMP, to the other or another side section in the seconddirection DR2. Thus, the curved display panel 30 and the curved window50 may be coupled (the curved display panel 30 may be laminated on thecurved window 50) sequentially from the one side portions in the seconddirection DR2 adjacent to the uppermost portions thereof to the otherside portions in the second direction DR2.

Accordingly, in the coupling process of the curved display panel 30 andthe curved window 50, air present between the curved display panel 30and the curved window 50 may be pushed outside the curved display panel30 and the curved window 50, and therefore it may be possible to preventair bubbles and the like from remaining between the curved display panel30 and the curved window 50.

The magnetic portion IMP_1 may move at the outside of the supportportion SPP while being spaced apart therefrom, in a direction from thecurved conductive portion MP3 to the first flat conductive portion MP1,or from the curved conductive portion MP3 to the second flat conductiveportion MP2.

For example, the magnetic portion IMP_1 may move from a portion adjacentto an uppermost end (one or an end in the second direction DR2) of theconductive portion MP to a lowermost end (the other or another end inthe second direction DR2) of the conductive portion MP. The magneticportion IMP_1 may move from the portion adjacent to the uppermost end(the one or an end in the second direction DR2) of the conductiveportion MP to a lowermost end of the first flat conductive portion MP1,and then may move again from the portion adjacent to the uppermost end(the one or an end in the second direction DR2) of the conductiveportion MP to a lowermost end of the second flat conductive portion MP2.

In an embodiment, the number of the magnetic portions IMP_1 may be two.For example, the magnetic portions IMP_1 may move from the portionadjacent to the uppermost end (the one or an end in the second directionDR2) of the conductive portion MP to the lowermost portions of the firstand second flat conductive portions MP1 and MP2, respectively.
